Metadata matching every scan now?

It seems for the past two to four weeks now every time I execute a scan (three dots next to Libraries, Scan Library Files) thousands of my files have meta-data matched during the scan process. These are existing files in my library, not new files. Each album, TV show, or Movie that this happens to will say three lines:
Finished processing X
Loading metadata for X
Downloading metadata for X

My previous 5 minute scan, for a 15 TB+ media library, is now an hour+ scan due to this. It happens every time now.

I checked through the Alerts log screen and realized that for the movie library it was specifically triggering on non-movie items incorrectly matched to movies or just ‘self-metadata’ (personal agent). Normally I didn’t mind all the non-movie items but the scan has been so bad that I went into my Movie library and consolidated (merged) all my non-movie items into a singular item (edited to say ‘not a real movie’). That cleared up about 900 items in my movie library so thanks for that I suppose. The scan still takes a very long time due to the amount of files this is happening on in Music & TV though. Unlike movies it’s happening on actual albums in the Music library. I’m using the Premium Music library, not sure if that makes a difference.

I run Version 1.12.1.4885 on Win10. My desktop is new(ish) and has corei7 & plenty of RAM.
I have never had an issue with scans taking a long time before or meta-data matching to already matched items. I manually kick off scans when I add new files as the ‘detect when a change is made’ takes anywhere from 30 to 60 minutes to pickup that a file was added, that’s too long when I want to watch it now. Personally I would very much wish my newest added file location would scan first instead of last in the library…I wish I could reorder the physical location scan order.

Any help or suggestions as to why this is happening?

@OttoKerner @sa2000
Is this a duplicate of @“Kyle Verry” 's issue?

@JamminR thanks! I believe the thread you linked is my exact problem. I’ll confirm tomorrow and will update this thread with your post as the right answer once I do.

Edit: I downgraded to verson 1.12.0.4829-6de959918 as specified in https://forums.plex.tv/discussion/comment/1643359/#Comment_1643359
Now my media scanner works as intended. Stinks there’s a bug, hopefully it’ll be fixed soon.

I would like to offer you a pre-release build with a fix for this - if you are happy to try and confirm the fix

Let me know

I presume it is windows

sa2000 sent me the pre-release build and I installed it in a Windows VM. The tagging behavior is no longer happening! :slight_smile: I can happily say it is fixed and back to expected behavior.

This is also happening for me with the official Docker image. It’s good to know it’s a known issue. Patiently waiting for fix. :slight_smile:

The fix for the repeated matching of unmatched music artists has now been released in beta release 1.13.0.5003
